Problem statement. To fully utilize the millimeter wave spectrum in 5G systems, it is planned to adopt a heterogeneous network (HetNet) architecture, in which modern 4G Internet access technologies operating within bands below 6 GHz are integrated with new broadband communication systems of the millimeter wavelength range. However, the deployment of heterogeneous networks in urban conditions that are difficult for the propagation of millimeter-wave radio signals imposes special requirements on antenna systems. Therefore, the development of cheap millimeter-range scanning antennas with a high gain and a working frequency band of several gigahertz is an urgent task.

Objective. The main purpose of this work was to develop a scanning antenna system of the 60 GHz band with a planar reflector combined with a compact phased array antenna (PAA) module.

Results. The measurement results have shown that the developed reflective array antenna within the band of 57.24-65.88 GHz, divided in accordance with IEEE 802.11ad and IEEE 802.11ay standards into four channels with a bandwidth of 2.16 GHz, has a high gain of 20.1-24.5 dBi and is capable of performing electronic beam scanning in the azimuthal plane in the ±15° sector. Moreover, the simulation results have shown that the full coverage sector in the azimuthal plane may potentially amount to ±35°.

Practical significance. The use of such antennas at both ends of reconfigurable relay communication lines will allow data to be transmitted over a distance of 100-150 m at a speed of 2.5-4.62 Gbps.
